erroneous Tokyo time

Hi there,

to be perfectly honest, I'm not sure if this bug is related to the Plasma desktop environment, Linux, GNU, or chrony, but since I couldn't find any information about this on other plattforms, this is most likely the best spot.

General description:
When I use a time zone different from my local time, the clock shows the wrong time.

My case:
My system time zone is Berlin, my additional time zone is Tokyo.

I guess, this is an issue with the time switch to summer time, since this wasn't erroneous before today.
When I change the system time zone to Tokyo, the time is correct.

System: Lenovo Yoga 7 14ASP9 83HN
OS: openSUSE Tumbleweed
Version: 20250328
Kernel: 6.13.8.1
Plasma: 6.3.3 Wayland

Greetings

Just to update you: Yes, it seems to be an issue with the time switch.
Now, that the time switch actually occured during the day, the Tokyo time is calculated correctly, when I configure Berlin as the system time.

This is probably an ICU problem, then. We don't mess with that in Plasma code; we just use what it gives us. I'd recommend reaching out to your distro about this; maybe they can nail down exactly what's going on.
